Using docker

To set up a local instance of the application using docker, follow the steps below.

Prerequisites

The following requirements are to be satisfied for the project to function properly:

• docker

(back to top)

Installation

1. Get the docker image

   You can get the docker image from either docker-hub or by buiilding it locally:

   • Pull from docker-hub

     sudo docker pull metakgporg/mftp-doctor

   • Build from Dockerfile
     • Clone the repository and cd into it

       git clone https://github.com/metakgp/mftp
       cd mftp/mftp-doctor

     • Build the image

       sudo docker build -t metakgporg/mftp-doctor .

2. Create a directory which will contain your env.py, name it as doctor_config

3. Follow the steps to configure env variables

Usage

Docker Compose

It is mandatory to provide the following env variable before the docker-compose command.

• DOCTOR_CONFIG: Absolute path to doctor_config directory

sudo DOCTOR_CONFIG=/path/to/doctor_config docker-compose up -d

(back to top)

Docker Command

This container requires access to hosts' docker.sock to check logs of mftp container running on host and the env.py file:

sudo docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /path/to/doctor_config/env.py:/mftp-doctor/env.py \
--name mftp-doctor \
metakgporg/mftp-doctor

(back to top)

As a cronjob

It is also possible to run these docker containers as a cronjob:

• With Docker Compose

  • Provide --cron as the DOCTOR_MODE env variable. For example:

    sudo DOCTOR_CONFIG=/path/to/doctor_config DOCTOR_MODE=--cron docker-compose up -d

• With Docker Command

  • Append --cron at the end of this commands, as follows:

      sudo docker run -d \
      -v /var/run/docker.sock:/var/run/docker.sock \
      -v /path/to/doctor_config/env.py:/mftp-doctor/env.py \
      --name mftp-doctor \
      metakgporg/mftp-doctor --cron

• Add the updated command with desired cron expression into your cronjob using crontab -e

(back to top)

Without using docker

To set up a local instance of the application without using docker, follow the steps below.

Prerequisites

The following requirements are to be satisfied for the project to function properly:

• python3 >=python3.10

  sudo apt update
  sudo apt install python3

(back to top)

Installation

Now that the environment has been set up and configured to properly compile and run the project, the next step is to download and configure the project locally on your system.

1. Clone the repository

   git clone https://github.com/metakgp/mftp
   cd mftp/mftp-doctor

2. Install required dependencies

   pip3 install -r requirements.txt

3. Configuring environment variables

   • Copy env.example.py as env.py. It looks like this:

     TOPIC_URL = "https://ntfy.sh/metakgp-mftp" # NTFY topic to send doctors' notifications on
     EMAIL = "abc@xyz.com" # Email to send doctors' notifications on

     You can read about you can learn about ntfy from their docs: https://docs.ntfy.sh/

   • Update the values inside the double quotes ("). DO NOT CHANGE VAR NAMES.

Usage

It is straight forward to use this script, just run it using supported version of python interpreter:

python3 mftp-doctor.py

It is also possible to bypass the continuous loop - which executes the code after every 2 minutes - using the --cron argument:

python3 mftp-doctor.py --cron
